Among the advantages of insert cutters is also the fact that they are very well-balanced and remain well-balanced throughout their life span. As long as no sharpening is done to the inserts, there are no weight changes, allowing for consistent cuts. This effect yields a cutter that can operate at higher RPM’s than most traditional cutters. The net advantage here is that although work loads per knife may be less, feed rates can be achieved with higher spindle speeds. One can also quickly notice less bearing fatigue due to the balance of the tool.
Contrary to earlier cutters, that only used straight knives, nowadays “custom profiled” cutter inserts are available. Some of the best examples in which custom profiles find great use are matching stile and rail cutters, corner miter joins. Using Insert cutters is especially beneficial because of the custom tool’s profile integrity.
The cost justification of insert cutters does not lie with the cutting tool user that only produces elaborate profiles for few production runs. However the advantages do become apparent to the manufacturer who has long production runs and sophisticated multi-spindle machines. Many insert cutters are now adaptable in width, making them more adaptable to multiple applications. All insert type cutters remain perfectly balanced and the cutting circle does not change. Another advantage insert cutters provide is the fact that they can be serviced on the machine, hereby further reducing machine downtime.
In many instances the insert cutters are less expensive than the sharpening of traditional carbide tipped tools.
Over the past 20 years, disposable cutter knives have proven themselves as precise, safe and cost-effective. With their established position especially when it comes to use on CNC machines, insert cutters are sure to evolve further and finding application in even more processes.
